Suppedaneum

A crucifix (from Latin cruci fixus meaning "(one) fixed to a cross") is an image of Jesus on the cross, as distinct from a bare cross. The representation of Jesus himself on the cross is referred to in English as the corpus (Latin for "body").

The crucifix is a principal symbol for many groups of Christians, and one of the most common forms of the Crucifixion in the arts. It is especially important in the Latin Rite of the Roman Catholic Church, but is also used in the Orthodox, Oriental Orthodox, Assyrian, and Eastern Catholic Churches, as well as by many Lutheran and Anglican churches. The symbol is less common in churches of other Protestant denominations, which prefer to use a cross without the figure of Jesus (the corpus). The crucifix emphasizes Jesus' sacrifice — his death by crucifixion, which Christians believe brought about the redemption of mankind. Most crucifixes portray Jesus on a Latin cross, rather than any other shape, such as a Tau cross or a Coptic cross.

Western crucifixes usually have a three-dimensional corpus, but in Eastern Orthodoxy Jesus' body is normally painted on the cross, or in low relief. Strictly speaking, to be a crucifix, the cross must be three-dimensional, but this distinction is not always observed. An entire painting of the Crucifixion of Jesus including a landscape background and other figures is not a crucifix either.
